Description

Die Erfindung betrifft eine Schlüssel-Schließzylinderkombination.The invention relates to a key-lock cylinder combination.

Bei den üblichen Schließzylindern, mit einem drehbar im Zylindergehäuse gelagerten Zylinderkern, sind die Zuhaltungen so angeordnet, dass sie durch das seitliche Profil des Schlüssels oder die Kerben in der Schlüsselbrust verschoben werden, wobei diese Verschiebung zu einem Abgleich der Gehäuse- und Kernzuhaltungen an der Trennebene zwischen Zylinderkern und Zylindergehäuse führt.In the conventional lock cylinders, with a cylinder core rotatably mounted in the cylinder housing, the tumblers are arranged to be displaced by the lateral profile of the key or the notches in the key-chest, this displacement to balance the housing and core tumblers at the parting plane between the cylinder core and the cylinder housing leads.

Während ohne einen eingeführten Schlüssel die Zuhaltungen diese Trennebene übertreten und so eine Drehung des Zylinderkernes verhindern, kann mit einem passend codierten Schlüssel der Zylinderkern gedreht und damit ein Schließvorgang ausgelöst werden. Das Dokument WO 2011/028713 A2 wurde nach dem Prioritätstag veröffentlicht und gehört somit zum Stand der Technik gemäß Artikel 54(3) EPÜ. Aus diesem Dokument ist es bekannt, die Zuhaltungen als Magnete auszubilden, die beim Einführen eines Schlüssels, der an seiner vorderen Spitze einen Magneten aufweist, verschoben werden.While the tumblers transgress this parting plane without an inserted key and thus prevent a rotation of the cylinder core, the cylinder core can be turned with a suitably coded key, thus triggering a closing process. The document WO 2011/028713 A2 was published after the priority date and thus forms part of the state of the art under Article 54 (3) EPC. From this document it is known to form the tumblers as magnets, which are displaced upon insertion of a key having a magnet at its front tip.

Voraussetzung für eine Schließmöglichkeit ist allerdings, dass der Schlüssel vollständig in den Schlüsselkanal einführbar ist, damit alle zusammenwirkenden Kerben, Profilbereiche und Zuhaltungen korrekt ausgerichtet sind.However, a prerequisite for a closing possibility is that the key can be inserted completely into the keyway, so that all interacting notches, profile areas and tumblers are correctly aligned.

Manipulationen eines derartigen Schließzylinders sind mit geeigneten Werkzeugen möglich, weil auch dieses Werkzeug im allgemeinen vollständig in den Schlüsselkanal einführbar ist. Das Dokument DE 100 00 528 A1 offenbart eine Schlüssel-Schließzylinderkombination gemäß dem Oberbegriff des Anspruchs 1. Aus diesem Dokument ist es bekannt, das vollständige Einführen eines falschen Schlüssels zu verhindern, weil erst ein zusätzlicher, in den Schlüsselkanal ragender, Sperrstift durch ein besonderes Merkmal am Schlüssel verschoben werden muss.Manipulations of such a lock cylinder are possible with suitable tools, because this tool is generally completely inserted into the keyway. The document DE 100 00 528 A1 discloses a key-lock combination according to the preamble of claim 1. From this document it is known to prevent the complete insertion of a false key, because only an additional, projecting into the key channel, locking pin must be moved by a special feature on the key.

Aufgabe der Erfindung ist es, die Sicherheit einer Schlüssel-Schließzylinderkombination mit einem derartigen Schließzylinder zu erhöhen.The object of the invention is to increase the security of a key-lock cylinder combination with such a lock cylinder.

Gelöst wird diese Aufgabe erfindungsgemäß mit einer Schlüssel-Schließzylinderkombination , mit einem im Zylindergehäuse drehbar gelagerten Zylinderkern, der einen Schlüsselkanal zu Einführen eines Schlüssels aufweist und wobei im Zylinderkern wie auch dem Zylindergehäuse miteinander und mit dem Schlüssel zusammenwirkende Kern - und Gehäusezuhaltungen vorgesehen sind, wobei mindestens ein zusätzlicher Sperrstift vorgesehen ist, der in einer Sperrstellung in den Schlüsselkanal hineinragt und dadurch das vollständige Einführen des Schlüssels verhindert und der durch ein im Schlüssel angeordnetes Merkmal in eine den Schlüsselkanal freigebende Freigabestellung bewegbar ist, wobei das im Schlüssel angeordnete Merkmal ein Magnet ist, dass dem zusätzlichen Sperrstift ein - bezogen auf den Magneten im Schlüssel - ungleich gepolter Magnet zugeordnet ist und dass im Zylinderkern oder Zylindergehäuse ein weiterer Magnet angeordnet ist, der so gepolt ist, dass er den Sperrstift solange in seiner Sperrstellung im Schlüsselkanal hält bis der Magnet im Schlüssel gegen die Wirkung des Magneten im Zylinderkern oder -gehäuse , den Sperrstift aus der Sperrstellung bewegt.This object is achieved according to the invention with a key-lock cylinder combination, with a cylinder housing rotatably mounted in the cylinder core, which has a key channel for inserting a key and in the Cylinder core as well as the cylinder housing together and are provided with the key cooperating core - and Gehäusezuhaltungen, wherein at least one additional locking pin is provided which protrudes into a locked position in the keyway and thereby prevents the complete insertion of the key and by a key arranged in the feature in a release the key channel release position is movable, wherein the key arranged in the feature is a magnet that is assigned to the additional locking pin - based on the magnet in the key - unevenly polarized magnet and that in the cylinder core or cylinder housing another magnet is arranged, the is poled so that it holds the locking pin in its locked position in the key channel until the magnet moves in the key against the action of the magnet in the cylinder core or housing, the locking pin from the locked position.

Gemäß der Erfindung ist ein zusätzlicher Sperrstift im Zylinderkern angeordnet, der so in den Schlüsselkanal hineinragt, dass ein Schlüssel nur soweit in den Schlüsselkanal einführbar ist, bis er an den Sperrstift anschlägt.According to the invention, an additional locking pin is arranged in the cylinder core, which protrudes into the keyway so that a key is only so far inserted into the keyway until it abuts against the locking pin.

Da diese Stellung keinem vollständigen Einführen entspricht, also der Schlüssel nicht an dem Sperrstift vorbei in seine Endstellung geschoben werden kann, lässt sich kein Schließvorgang ausführen.Since this position does not correspond to a complete insertion, so the key can not be pushed past the locking pin in its end position, no closing operation can be performed.

Diese Ausbildung des Sperrstiftes hat nichts mit der Ausbildung eines Zuhaltungsstiftes zu tun, der beispielsweise durch eine Magnetanordnung in sein Abgleichlage an der Trennebene Zylinderkern/Schließzylindergehäuse gedrückt wird, weil hierzu das vollständige Einführen des Schlüssels notwendig ist.This design of the locking pin has nothing to do with the formation of a tumbler pin, which is pressed for example by a magnet assembly in its adjustment position on the parting plane cylinder core / lock cylinder housing, because this is the complete insertion of the key is necessary.

Damit die Sperrung des Schlüsselkanals beibehalten werden kann, ist vorgesehen, dass auf den zusätzlichen Sperrstift eine Magnetkraft einwirkt, die den Sperrstift in den Schlüsselkanal hineinzieht.
Dies wird durch einen im Zylinderkern oder Zylindergehäuse positionierten Magneten erreicht, dessen Polung einem am Sperrstift vorgesehenen Magneten ungleich ist.Thus, the blocking of the keyway can be maintained, it is provided that acts on the additional locking pin, a magnetic force that pulls the locking pin in the keyway.
This is achieved by a magnet positioned in the cylinder core or cylinder housing whose polarity is unequal to a magnet provided on the locking pin.

Ebenfalls mit einem Magneten, und zwar in seinem Bereich nahe oder in der Schlüsselspitze, versehen ist der Schlüssel. Dieser Magnet ist nun so ausgerichtet, dass er gleichpolig zu der Polung des Magneten am Sperrstiftes wirkt.
Das Magnetfeld des Magneten im bzw. am Schlüssel, sollte so ausgebildet sein, dass es der Einführrichtung des Schlüssel beim Einführen in den Schlüsselkanal vorauseilt.Also provided with a magnet, in its area near or in the key tip, is the key. This magnet is now aligned so that it acts gleichpolig to the polarity of the magnet on the locking pin.
The magnetic field of the magnet in or on the key, should be designed so that it Insertion direction of the key when inserting into the key channel leads.

Aufgrund der unterschiedlichen Polungen wird durch den sich beim Einführen dem Sperrstift nähernden Schlüssel das Magnetfeld des im Zylinderkern oder Zylindergehäuse angeordneten Magneten überlagert, der Sperrstift abgestoßen und aus dem Schlüsselkanal entfernt, so dass der Schlüssel weiter in seine Schließposition geschoben oder eingeführt werden kann.Due to the different polarities is superimposed by the magnet in the cylinder core or cylinder housing arranged magnet during insertion of the locking pin, the locking pin repelled and removed from the keyway, so that the key can be pushed or introduced into its closed position.

Vorzugsweise handelt es sich bei den Magneten um Permanentmagnete, jedoch sind auch Elektromagneten oder Kombinationen beider Magnetarten anwendbar.Preferably, the magnets are permanent magnets, but also electromagnets or combinations of both types of magnets are applicable.

Nach einer Ausführung der Erfindung ist der Sperrstift L-förmig ausgebildet, wobei der vom Sperrstift ausgehende Arm, der nicht in den Schlüsselkanal hineinragt muss, einen Magneten trägt, der - in der Einführrichtung des Schlüssels - dem Sperrstift vorgelagert ist.According to one embodiment of the invention, the locking pin is L-shaped, wherein the outgoing of the locking pin arm, which does not protrude into the keyway, carries a magnet which - is preceded - in the direction of insertion of the key - the locking pin.

Auf diese Weise wird die vorher beschriebene Verschiebung oder das Abstoßen des Sperrstiftes in Bezug auf den Schlüsselkanal unmittelbar vor dem Auftreffen der Schlüsselspitze auf den Sperrstiftstift erfolgen, so dass dieser für das vollständige Einführen des Schlüssels frei gegeben wird.In this way, the previously described displacement or repulsion of the locking pin with respect to the keyway will occur just prior to the impact of the key tip on the locking pin so that it will be released for complete insertion of the key.

Die Erfindung soll nachfolgend an Ausführungsbeispielen mit Bezug auf die Zeichnungen beschrieben werden.The invention is based on embodiments with reference to the drawings to be discribed.

Dabei zeigt:

  • Fig. 1, 2 eine schematische Schnittdarstellung durch den Zylinderkern mit eingeführtem Schlüssel bei geschlossener und offener Position des Sperrstiftes in magnetischer Ausführung
  • Fig. 3, 4 eine abgewandelte magnetische Ausführung mit entsprechenden Positionen des Sperrstiftes.
Showing:
  • Fig. 1 . 2 a schematic sectional view through the cylinder core with inserted key in the closed and open position of the locking pin in a magnetic design
  • Fig. 3 . 4 a modified magnetic design with corresponding positions of the locking pin.

Bei allen dargestellten Ausführungen sind gleiche Teile mit den gleichen Bezugszeichen versehen.
So ist mit 1 der Zylinderkern bezeichnet, der in bekannter Weise in einem Schließzylindergehäuse drehbar gelagert ist. Auf die Darstellung dieses Gehäuses wurde hier verzichtet.
In dem Zylinderkern 1 befindet sich der Schlüsselkanal 8, in den der Schlüssel 2 einführbar ist.In all the illustrated embodiments, the same parts are provided with the same reference numerals.
Thus, denoted by 1 of the cylinder core, which is rotatably mounted in a known manner in a lock cylinder housing. On the presentation of this case was omitted here.
In the cylinder core 1 is the key channel 8, in which the key 2 is inserted.

Auch hierbei wurde die Darstellung vereinfacht, d. h. die üblichen Zuhaltungen 12 wurden nur angedeutet.Again, the presentation has been simplified, d. H. the usual tumblers 12 were only hinted at.

Der Kern der Erfindung liegt in dem Einsatz eines Sperrstiftes 5, der im Normalzustand - wenn sich kein Schlüssel in seinem Verschiebungsbereich oder Hubbereich befindet - soweit in den Schlüsselkanal 8 hineinragt, dass ein teilweise eingeführter Schlüssel an seinem weiteren Vorschub durch den Sperrstift gehindert wird. Bezogen auf den Längsschnitt durch den Zylinderkern ist der Sperrstift radial verschiebbar.The essence of the invention lies in the use of a locking pin 5, which in the normal state - if there is no key in its displacement range or stroke area - so far projects into the keyway 8 that a partially inserted key is prevented from further advancing by the locking pin. Based on the longitudinal section through the cylinder core of the locking pin is radially displaceable.

Bei der Ausführung nach den Figuren 1 und 2 , ist der Sperrstift an seinem einen Ende von einem ringförmigen Magneten 6 umgeben, der sich mit dem Sperrstift in einer entsprechenden Bohrung des Zylinderkernes bewegen kann. Dem freien Ende des Sperrstiftes 5 im Kern gegenüberliegend ist ein weiterer Magnet 4 angeordnet, wobei die Polung der Magneten 4 und 6 so gewählt ist, dass zwischen beiden eine Anziehungskraft wirkt, d. h. der Sperrstift 5 wird mit seinem Magneten 6 vom Magneten 4 angezogen, so dass der Sperrstift 5 in seiner Position gehalten wird, die den Schlüsselkanal blockiert oder verschließt.In the execution of the FIGS. 1 and 2 , the locking pin is surrounded at its one end by an annular magnet 6 which can move with the locking pin in a corresponding bore of the cylinder core. The free end of the Locking pin 5 in the core opposite another magnet 4 is arranged, wherein the polarity of the magnets 4 and 6 is chosen so that an attraction between both acts, ie the locking pin 5 is attracted with its magnet 6 from the magnet 4, so that the locking pin. 5 held in its position, which blocks or closes the key channel.

Die Spitze oder der vordere Bereich des Schlüssels 2 ist ebenfalls mit einem Magneten versehen, der mit 3 bezeichnet ist.
Die Polung dieses Magneten 3 ist nun so, dass der mit dem Sperrstift 5 bewegliche Magnet 6 abgestoßen wird. Damit wird der Sperrstift in seine Bohrung zurück gedrückt und gibt den Schlüsselkanal 8 frei, so dass der Schlüssel 2 weiter in diesen eingeführt werden kann, bis er seine Endstellung erreicht, in der ein Schließvorgang ausführbar ist.The tip or the front portion of the key 2 is also provided with a magnet, which is designated 3.
The polarity of this magnet 3 is now such that the magnet 6 which is movable with the locking pin 5 is repelled. Thus, the locking pin is pushed back into its bore and releases the key channel 8, so that the key 2 can be further inserted into this until it reaches its end position in which a closing operation is executable.

Diese Wirkungsweise ist vergleichbar mit der bei der Ausführung nach den Figuren 3 und 4. Der Unterschied liegt nur in der Ausbildung oder Gestaltung des Sperrstiftes 5.This mode of action is comparable to that in the execution of the Figures 3 and 4 , The difference lies only in the design or design of the locking pin. 5

Im Gegensatz zu dem ringförmigen Magneten 6 ist bei dieser Ausführung der Sperrstift mit einem L-förmigen Arm 7 versehen, der den Magneten 6' trägt.
Dieser Magnet ist dem Sperrstift damit vorgelagert, d. h. der Schlüssel nähert sich mit seinem Magneten 3 erst dem Magneten 6' und dann dem Sperrstift 5.
Unter der Wirkung der Gleichausrichtung der Polung der Magneten 3 und 6' wird der Sperrstift 5 bewegt (Figur 4) und gibt damit den Schlüsselkanal 8 frei.In contrast to the annular magnet 6, in this embodiment, the locking pin is provided with an L-shaped arm 7, which carries the magnet 6 '.
This magnet is upstream of the locking pin, ie the key approaches with its magnet 3 only the magnet 6 'and then the locking pin. 5
Under the effect of the alignment of the polarity of the magnets 3 and 6 ', the locking pin 5 is moved ( FIG. 4 ) and thus releases the key channel 8.
